World of math removed from courses.

I am a supplementary instructor in Atlanta, GA, US.

As such, I am not truly bound to the standards set in traditional educational systems.

Since I find that when it comes to mathematics (having a background in it myself) that a student will have trouble with the "ruthlessly cumulative" nature of the subject (not my phrasing but one I am apt to use), I address what they are working on in grade level along with making them do ALL of Khan Academy, from Kindergarten on up.

This has worked exceptionally well for the last ten years so much so that a local school wants to try this approach.

When I set up the class this evening, I found that I could not construct a class under the course of "World of Math" like I used to be able to.

Am I missing something, or is there a way I can construct a class under completing all of the exercises available on Khan Academy.

Thanks,

Jonathan William
